Using public transport during your stay in the Algarve is an option you may wish to explore. It is inexpensive and fairly punctual, but does require a little research before you set off.
EVA buses (www.eva-bus.com) run a good local and regional service. The company also offers services to Lisbon, as does Rede Nacional de Expressos www.rede-expressos.pt. Buses are clean and prices reasonable. The local services within resorts can be a little more haphazard. However, some towns such as Albufeira and Portimão, have new shuttle type services covering the town and close resorts. For example the "Vai Vem" in Portimão serves not only the town but also Praia da Rocha, Praia do Vau and Alvor. Buses run every 30 minutes and a day pass costs 3,50 €.
The trains in Portugal are run by the Caminhos de Ferro Portugueses www.cp.pt. They are clean, cheap and punctual. You can travel right across the Algarve, from Lagos to Vila Real de Santo António on the Spanish border, by local train. Although not the fastest way to cover ground, the trains’ routes often offer much better scenery than the highways, and the pace is definitely more relaxed.
